摘要
鉴于资本监管、货币政策对商业银行效率的重要影响,本文在Li和Wang(2012)的基础上从理论上详细论证了坏账率、资本充足率和准备金率影响商业银行效率的内生机制,并得出研究命题:坏账率与商业银行成本效率、利润效率存在着负相关关系;资本充足率、准备金率与商业银行成本效率、利润效率存在着非线性关系和非对称效应。根据上述研究命题,利用商业银行1998-2010年我国14家商业银行相关数据计算出了商业银行的成本效率、利润效率,证实了准备金率、资本充足率与商业银行的成本效率、利润效率呈非线性关系以及商业银行效率的非对称效应。上述研究事实表明:过分强调资本监管和货币政策对于商业银行绩效的改善是不合适的,其虽然能够有效地控制风险,但同时也会带来"利润创造能力"的减弱。因此,合理的资本监管和货币政策才是提高商业银行效率的明智之举。
Owing to the important influences imposed by capital regulationand monetary policy,we get the endogenous mechanism on how the rate of noneperformingloan （NPL）, capitalade quacy （CAR） and statutory reserve （SRR） fluences the bank＇s efficiency through Liand Wang（2012） ,and then make the conclusion that NPL is inversely proportional to the commercial banks＇ costand profit efficiency. What＇ s more,the nonlinear relationship and asymmetry effects are found among CAR,SRR and the bank＇ s cost and profit efficiency. Based on the judgment above ,this paper calculates the cost and profit efficiency with 14 listed commercial bank＇s relevant data from 1998 to 2010,and the Panel Threshold Model is used to prove the nonlinear relationship and asymmetry effects,which shows that excessively regulation has great harmful effects on the commercial banks. It cannot only minimize the risk effectively, but also limit the ability of ＂profit creating＂. Therefore,the reasonable capital regulation and other prudential supervision measures should be emphasized.
